Discoloration is one of the most commonly seen cosmetic problems. Some of the more common causes for stains are:
• Food and drinks – drinking coffee is infamous for causing tooth discoloration, but tea, colas and wines also have the same effect. Some choice fruits and vegetables can also cause tooth stains. Consuming any of these can contribute to discoloration.
• Smoking – Due to the presence of nicotine and tar, teeth become yellow, which eventually turn brown after extended exposure to cigarette smoke.
• Poor Oral hygiene – bad dental habits such as neglecting to brush or floss can lead to plaque build-up, which results in discoloration later on as well.
The truth is, however, even avoiding above named common substances we may still see dulling in our smile over time. Most of the stains that we notice have occurred over several years. It is because of the longevity of stains in the enamel that commercial whitening products are generally ineffective at producing optimal results. To reach stains in the deeper layers of enamel takes a more powerful yet safe product, one that is available at your dentist.
